Android HDMI输出竖屏问题

你是做系统吗？你要先确认下你用的方案的hdmi输出的做法是什么样子的，各家都不太一样，最好直接问方案商。

谢谢回答BSP提供方应该不会就这些问题作解答的，原始BSP是三星的，然后移植过来发现问题不少，就自己排查了些。

三星的话，应该是通过android层的hwc来实现的，你可以dumpsys SurfaceFlinger 确认下是不是有两个display 设备。如果是hwc实现的话，那原因应该是hdmi和panel在方向上的差异，你可以debug下LocalDisplay里面的configureDisplayInTransactionLocked()，这个是在输出前设置display的信息的，可以尝试调整下hdmi display的方向。

看来你也是做系统的呀。这是我dumpsys之后的信息：

我之前一直在device/samsung/exynos4/libhdmi/目录里面调的，主要还在看SecHdmi.cpp这个文件，主要是没有方向，摸索了很久了，我现在按照你的方向先看一看，谢谢！

你好，我在我的源码里搜不到跟configureDisplayInTransactionLocked有关的文件，可否给个参考呢？

你这个好像不是用的hwc来做的，那就不用看那个代码了。
